Strait of Georgia Central Current Meter Deployed 2011-07-03

The Nortek Vector Current Meter 4820 was deployed on 2011-07-03 at Strait of Georgia Central. Strait of Georgia Central is a central area in the Strait of Georgia. This device is a Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current metres have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

诺泰克Vector 4820型海流计（Nortek Vector Current Meter 4820）于2011年7月3日部署于乔治亚海峡中部（Strait of Georgia Central）。乔治亚海峡中部是乔治亚海峡的中心区域。该设备属于海流计范畴。声学海流计（Acoustic Current Meters，ACM）借助多普勒效应测量海流的流速与流向。Aquadopp型海流计的传感器探头包含3个声学换能器、1个倾斜传感器、1个温度传感器与1个压力传感器。该仪器发射短脉冲声波，随后监听回波以测量音高或频率的变化，通过音高变化即可确定海流的流速。本次部署采用固定式平台搭载设备。本次采集的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外开放共享；相关数据已完成质量管控，且衍生数据产品均遵循既定行业规范生成。
